Phlegm Target
A term used to describe someone who is so wretched and nasty (Slag Pile) that they deserve to be spit upon. However when this person is so bad, ordinary spit is not good enough for them. One must hack up some really gross phlegm and spew at them.
That guy/gal hosed me so bad, the only reason for his/her existence is to be my personal phlegm target.
